Lifetime enhancement of organic photovoltaic cells by using self-organized polymeric anodes |
| 초록 |
Flexible transparent electrode materials in organic optoelectronics have received the great attention to replace conventional brittle inorganic oxide materials. Self-organized polymeric anode materials were prepared based on poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate)(PEDOT:PSS) in which 5wt% DMSO were added to enhance their conductivity. As a key component, perfluorinated ionomer(PFI) was included to achieve a high work function and hydrophobicity. They showed excellent tuning of work-function which enabled to outperform the conventional ITO. The maximum work-function of the anode is 5.8 eV which is the highest value among the flexible anodes which have been reported until now. Moreover, transparency was higher than 90 % in all the visible range. We applied these conducting polymer anodes to bulk-hetero junction organic photovoltaic cells(OPVs). The lifetime of the OPVs was highly enhanced compared with the conventional ones with an ITO anode. |
